apparat (DISCONTINUED!)

this was an experiment. don't use it. promises are a much better way to organize async code in nodejs!

Build Status

apparat is a simple but powerful way to organize async code for nodejs

install

npm install apparat

use

read domain from file domain.txt.

write resolved IPV4 addresses to addresses4.txt and write resolved IPV6 addresses to addresses6.txt in parallel.

remove domain.txt when both files have been written successfully.

fs = require 'fs'
dns = require 'dns'

apparat = require 'apparat'

{receive, send, onError, debug} = apparat

debug console.log
onError (err) -> throw err

fs.readFile 'domain.txt', send 'contents'

receive 'contents', (contents) ->
    domain = contents.toString().trim()
    # parallel
    dns.resolve4 domain, send 'addresses4'
    dns.resolve6 domain, send 'addresses6'

receive 'addresses4', (addresses) ->
    fs.writeFile 'addresses4.txt', addresses.join('\n'), send 'addresses4 written'

receive 'addresses6', (addresses) ->
    fs.writeFile 'addresses6.txt', addresses.join('\n'), send 'addresses6 written'

receive 'addresses4 written', 'addresses6 written', ->
    fs.unlink 'domain.txt', send 'deleted'

receive 'deleted', ->
    console.log 'OK'
